Reason I ask is that I have tried various setups on past vehicles and its been hit or miss. What was a waste of time on 1 car was good on another. Last car was just basic cone on end of pipe. No heatshield, no fenderwell install. Just basic and worked fine. This time around I see no reason to do more work than needed for same amount of gain. I actually like the quiet of the car but will change if needed. Right now I am about to gut the airbox but I might also have some parts to put in a cone style filter by the front headlight. What I am curious about is if there are any numbers to back up claims and not just opinion cause that isn't always accurate. The cone right off the tb has me intrigued on wether its good not
